PEA-HULLING MACHINE.

SPECIFICATION forming part of "Letters Patent No.' 752,256, dated February 16, 1904.

Application filed September 80, 1803. Serial No. 176,213. (Remodel) rt all! whom it may concern:

Be it known that we, WILLIAM F. PILLMOR and DAvrqAupnance, citizens of the United States, res ding at Westernville, in the county of Oneida and State-of New York-have .invented a new and useful Pea-Hulling Machine, of which the following is a specification.

This invention relates to machines forihulling peas, and it is an improvement on the machine of this class for which Letters Patent of the United States No. 728,759were granted to us on' the 19th day of May, 1903.- A

In'the said Letters Patent ispresented a separating-drum supported revo'lubly and presenting an unobstructed-"interior, a plurality of beater-drums disposed longitudinally within and rotating in the same direction as the separating-drum and distributed about its central or axial space and provided with ribs or-beating devices, vine-lifting ribs upon the aside of the separating-drum, and means for feeding the vines'into thev'central space between the beater-drums, which constitutes a conveyor-channel through which the vines the machine.

mainly travel during their passage through While the construction thus generally expressed has been found extremely useful and while it has been found to operate to perfection upon pea-vines under ordinary circumstances, we have discovered, that a superior result may be attained by certain changes, which'are the subject of the present application. These changes consist, first, in making the beater-drums .frustum-shaped-in' stead of cylindrical, asshown in our patent above referred to, the vines being fed -between l the wide ends of the frustum-shaped beater-' drums. This construction is especially use- 7 ful when the vines that are operated upon are quite long, inasmuch as said vines during the operation of the machine are apt to'and,in fact, are intended to escape from the central space between the beater drums into the space between said beater-drums. and the exterior cylinder.- Now when short vines are operated upon thesewill readilyreturn into the central space, where they are subjected to the-most violent action-of the heaters or agitators.-

Long vines, however, will'not return so readily :with our invention.

sectional viewofthe same, taken on the line 2 2 experience that the increasing distance between the perimeters of the beater-drums will greatly facilitate the ingress between them of the material to be operated upon.

Secondly, our patented device is improved by disposing the lifting-ribs upon the inside of the exterior cylinder in a somewhat inclined position, whereby we find that the-operation will be facilitated.

Thirdly, our improvement contemplates the disposition beneath the separating-drum of a plurality ofendless aprons, which will serve to separate from the peas any impurities in the way of chaif, small pieces of pods or vines, dirt, and the like which it is extremely desirable to separate from the peas at as early a stage as possible.

Our invention, then, consists in the. improved construction, arrangement, and combination of parts, which will be hereinafterfully described, and particularly pointed out in the claims.

In the accompanying drawings, Figure l is f l a vertical longitudinal sectional view taken through a machine constructed in accordance Fig. 2 is a transverse in Fig. 1. 7

Corresponding parts in'bothfigur'es are indicated by similarnumeralsof reference.

1 designates a suitably-constructed frame, in-which are journaled rollers 2, supporting the separating-cylinder 3, which is provided with a plurality of perforations 4 of suitable diameter to permit the peas to escape therefrom. This cylinder andlt's exterior surface -m'ay be constructed of any suitable material.

Interiorly upon the cylinder are disposed a plurality of vine-lifting ribs 5, which are disposed obliquely, as shown, and which-when the machine is in operation have a screw action, which assists in delivering the vines elethe centralline'or axis of the cylinder. Suitbetween the latter and the exterior cylinder.

. less apron or carrier 9 being disposed slightly which appear in the accompanying drawings.

of the machine the space between said drum increases gradually and that consequently machine are operated upon mainly while disposed in the said central space, will bereadtrough or casing forming areceptacle for the peas. We now arrange under the separatingwhat less inclination than the aprons 9 and rated ti e liftingaibs in the direction of ably disposed within the cylinder and in bearings provided. therefor in the frame of the machine are a plurality of shafts 6, three of We would desire it to be understood, however, that rnore than three of these shafts and their relatedparts may be utilized without departing from the spirit of the invention; These shafts, it will be observed, are disposed equidistantly apart and all at equal distances from the axis of the separating-cylinder. These shafts 6 carry the beater-drums 7, which instead of being cylindrical, as in our former patent, are made frustum-shape'd, their large ends being disposed at the feed end of the.

'machine, where a hopper 8 is provided for the purpose of feeding the material operated upon into the space between the beater-drums. It is obvious that owing to the decreasing di ameter of the latter toward the discharge end the vines, which during the operation of the ily returnable into said central space in the event of their having found an exit between any two of the beater-drums into the space The discharge ends of the beater-drums are extended beyond the discharge end of the separating-cylinder for the purpose of discharging the helm beyond said cylinder, and the shafts of said drums are provided with pul-. leys to receive motion from any suitable source of power, whereby they and the separatingcylinder may be rotated simultaneously in the Same direction.

Under the provisions of our former patent the separating-cylinder was disposed above a cylinder a pair of endless carriers 9 and 10, consisting of wide aprons mounted upon suitable rollers 9 and 10*,the lower end of the endabove the lower end of the apron 10. A third apron 11 is mounted upon rollers 11 beneath the discharge end of the apron 10, said apron 11 inclining in the direction of 'a receiver 12. It is obvious that when the machine is in operation the peas will drop upon the aprons 9 and 10, the upper leads of which move in an upward direction. The peas being round will roll down the said aprons, those dropping upon the apron 9 rolling over upon the lower end of the apron 10 and passing from thence to the'apron 11, WhlCl'blS disposed at a some- 10. Bits of stalks, pods, and the like will adhere to and be carried upward by the aprons 9 and 10 and be discharged at the upper ends of the latter into suitable recepbeing employed, if necessary, in order to re move the waste matter. The finalseparation of the peas from objectionable matter will take place upon the apron 11, which being disposed'ata less inclination than the aprons 9 and' 10 will make it practically impossible for waste material to escape into the receptacle provided for the peas.

In practice the outer drum and the beaterdrfims are all driven in the same direction, as will be found indicated by arrows or darts upon Fig. 2 of the drawings, said beaterdrums being rotated at a relatively high rate of speed, as shown by the heavy darts.

The operation of the device is as follows: The pea-vines are fed into the chute or hopper 8, passing from thence into the space between the rapidly-rotating beater drums or cylinders. I No care need be taken to feed the material slowly or evenly, inasmuch as as soon as a bunch of the vines enters the space between the beater-drums it will be violently torn asunder and subjected to the threshing action of the'beaters. When, as in the present instance, three beater-drums are used, the material fed between said drums will be forced by the action of each drum in an outward direction toward the outer drum. A portion of the vines will pass into contact with said outer drum. The greater proportion. however, will adhere to the heaters and be carried over or around the latter into the central space. It will also be seen that such portion of the vines as passes'into contact with the inside of the outer drum will be elevated by the ribs of the latter until it reaches a point even with or slightly above the uppermost drum, the screw action of the ribs serving to elevate the front ends of the vines. The tendency of the vines will be to drop upon said drum and the tendency of the beaters upon the latter will be to carry the vines into the central space between the drums. The tendency of the heaters upon the one drum to seize the vines and throw them outward against the inner wall of the outer drum will be counteracted by the heaters upon the next, the tendency of which will be to throw the vines. toward the next succeeding. It will thus be seen that the vines and pods, by the combined action of the several drums, will be violently threshed and agitated and that the tendency of the combined action of the three inner drums will be to retain the vines or halm between the said drums. It is not intended thereby to assert that the vines, pods, &c., are retained entirely in the space between thesaid beater-drums, but by far the larger proportion is thus retained and will be progressively fed toward the discharge end of the machine, while the smaller and especially the heavier particles, including necessarily th shelled peas, will escape tothe outer drum, through the perforations of which they pass to the cleaners. Thus while the agitation to which the pea-vines is subjected is excessiv'e from a standpoint of rapidity of action the beating they receive does not result in any damage, such as bruising or mashing of the peas, they being protected by the helm, from which theyare readily separated and permitted to pass to the outer drum. The disposito the precise structural detailsherein shown, but reserve the right to any changes, altera-' tions', or modifications which may be resorted to within the scope {of -our invention and without-departing from the spirit or sacrific ing the utility of the same.

, Haying thus described our invention, we claim- 1-. In a machine of the class descri-hed,-a separating-drum supportedrevolublyand pres. senting an unobstructed interior, a plurality of frustumshaped beater-drums disposed lonour own we have hereto afiixed. our signatures gitudinally within and rotated in the same di: rection as the separating-drum and distributed about its central or axial space, said, heaterdrums being provided with beater-ribs and said beater-drums being disposed with their large ends'at the feed end of the machine and? decreasing in diameter toward the discharge end of the machine,'vine-lifting ribs disposed obliquely upon the inside of the separatingdrum, and means for feeding the vines into the central space between the beater drums, which constitutes a conveyer-channe'l through which the vines. mainly travel during their passage through the machine.

2. In a machine of the class described, the combination of an external drum adapted to revolve and provided with interiorlydisposed oblique vine-lifting ribs, and a plurality of interior beating and'conducting drums arranged inside thereof, equidistantly from each other and equidistant'from the axis of the external drum, said beater-drums being frustunm shaped and disposed with their large ends at the receiving end of the machine.

3. In' a machine of the class described, the
